Mobil Hydraulic Oil DTE 25 1 Gal (ISO VG 46) — Anti‑Wear, Thermal Stability

Mobil DTE 25 combines controlled viscosity, thermal stability, and anti-wear performance in a 1-gallon package ideal for workshops, fleets, and industrial maintenance. Designed by Mobil and manufactured in the United States, this formulation suits systems that require ISO VG 46 fluids and need reliable lubrication, oxidation resistance, and fluidity down to moderately low temperatures.

How does Mobil DTE 25 support hydraulic component longevity?

This hydraulic oil contains anti-wear additives and oxidation inhibitors to minimize wear, deposits, and viscosity increase over time. By controlling metal-to-metal contact and preventing sludge formation, it helps maintain pump and valve performance under continuous use.

• ISO VG 46 base viscosity for consistent film strength
• Anti-wear chemistry to reduce component scuffing
• Oxidation inhibitors slow varnish and sludge buildup
• Flash point of 395°F indicates thermal robustness

What operating temperatures and viscosity behavior can I expect?

Mobil DTE 25 is formulated to hold its viscosity at typical operating temperatures, with a SUS of 238 at 100°F and an ISO VG 46 rating. The pour point of -10°F allows reasonable cold-start performance in moderate climates, while the high flash point supports safe operation at elevated temperatures.

• ISO Viscosity Grade: 46 for balanced flow and film strength
• Viscosity SUS @ 100°F: 238 for predictable hydraulic response
• Pour point -10°F for satisfactory low-temperature startup
• Flash point 395°F for thermal safety margins

How should I use this 1-gallon container in maintenance and repair?

The 1-gallon size is convenient for topping off reservoirs, on-site repairs, or smaller systems where bulk drums are unnecessary. Always consult the equipment manufacturer for recommended viscosity grade and change intervals; use clean funnels and filtration when adding fluid to prevent contamination.

• Ideal for topping off hydraulic reservoirs and mobile equipment
• Useful for workshops, service trucks, and small systems
• Follow OEM viscosity and cleanliness specifications
• Use proper filtration to maintain fluid life

Will Mobil DTE 25 work with my existing hydraulic fluid?

Mobil DTE 25 is compatible with many mineral-based hydraulic fluids, but compatibility can vary depending on additive packages. Before mixing, check the current fluid’s specifications and, if possible, consult Mobil technical resources or perform a small compatibility test to avoid undesirable interactions.

• Generally compatible with other mineral hydraulic oils
• Mixing with unknown formulations can alter performance
• When in doubt, drain and replace to ensure optimal protection
• Manufacturer support available for specific compatibility questions

Who is this for? Mobil DTE 25 in a 1-gallon container is aimed at technicians, fleet managers, and maintenance professionals who need a dependable ISO VG 46 hydraulic oil for routine service, smaller systems, or field repairs. It fits users who prioritize anti-wear protection, thermal stability, and the convenience of a manageable container size produced by a trusted manufacturer.
